GAS STOVE OR HEATER.

SPECIFICATION forming part of Letters Patent No. 787,829, dated April 18, 1905.

Application filed January 19, 1905. Serial No. 241,834.

I!) ui/ 11-71mm t may concern.-

Be it known that I, HERBERT CLAYTON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful improvements in Gas Stoves or Heaters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in gas stoves or heaters, and pertains to that class which is especially adapted to be applied to the ordinary gas-burner tips and which operates on the Bunsen principle to 1 produce a blue heating-flame.

The primary objects of my present invention pertain to providing a mixing-conduit extending into the receivingchamber, whereby a more thorough intermingling of the gas and air accomplished and a better and more perfect blue flame produced by the burner, and to provide peculiar elongated or slit-shaped burner exit-openings, whereby an improved result is accomplished.

My present invention has in view certain other details of construction, which will be specifically explained hereinafter.

In the accompanying drawings, Figure l is a perspective view of my improved burner. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is an enlarged dileta view of the elongated or slit-shaped exit burner-openings. Fig. 4 is a detached in verted view of the upper supporting member or grate and its cooperating members. Fig. 13 is an enlarged horizontal section through a portion of the chamber-wall which contains the burner-slits.

in carrying out my invention I use the usual buruer-tip-receiving nozzle 1, to which the lower end of a sheet-metal receiving and mixing member 2 is attached by bending in its lower edge under the upper walls of the air-inlet openings 3, as shown at l:. The lower end or portion of the receiver or mixer 2 is conical in shape, as shown at 5, and its upper portion terminates in a relatively restricted mixing pipe or tube 6, which extends upward within the receiving shell or chamber 7. This receiving chamber or shell 7 is essentially an inverted truncated cone, and the upper end of the shell 7 is pro vided with peculiar burner exitopenings and deflectors to constitute the burner proper, S, and which will be specifically described here- .inafter.

Placed upon the upper end of the burner 8 is a closure and utensil-supporting member, which consists of a ring E), provided with radially-projecting arms 10 to receive the utensil or vessel or other object that is to be heated. The under side of this ring 9 is recessed, as shown at ll, to receive the lateral llange l2, surrounding and projecting outwardly from the upper edge of the burner S. This recess ll is made sufficiently deep to also receive a sheet-metal disk 14 to close the opening of the ring 5). Projecting inwardly over this recess are a suitable number of prongs 15, under which the flange l2 of the burner is adapted to interlock for the purpose of uniting and holding the ring, the flange of the burner, and the disk in the positions shown in Figs. 1 and 2. In order to enable the ring and disk to be removed from the burner or upper end of the shelf 7, the flange 12 is provided with a slot or recess 16, which can be turned to register with one of the prongs l5, and thus enable the parts to be separated and to be readily connected.

The burner 8, as previously stated, is peculiar in its construction and consists of a plurality of elongated or slit-shaped openings 17, which are preferably extended in an inclined, diagonal, or oblique direction. The walls 18, between these exit-openings l7, constitute deflectors and extend in a direction which will cause the outilowing mixture to pass in a direction substantially tangential to the outer surface of the burner, and thus have a tendency to travel around adjacent to the outer wall of the burner instead of radially or directly away from the outer wall of the burner. This construction causes the llame to cling adjacent to the wall of the burner and to more directly impinge upon the under side of the object being heated than is the case where the issuing flame is directed in a radial line. From the foregoing it will be understood that the deflectors 18 extend in a direction tending to the tangential and because of this direction produce the result just mentioned. The obj ect of having the slits or elongated openings diagonally arranged is to cause the issuing gases and flames from the several slits to substantially overlap each other in a verti cal line and to thus cause a joinder of the several flames or gases, and thus produce substantially a solid flame as contradistinguished from a plurality of elongated flames, which would be the case if the slits were ar ranged substantially in a vertical line.

By reference to Fig. 2 it will be noted that the lower edge of the shell 7 rests upon a shoulder 19, located or formed at the junction of the cone-shaped portion 5 and the mixing-tube 6. The shell and mixer are united by swaging the metal of the mixer downward upon the lower edge of the shell, which produces a substantial connection of the two parts.

I do not desire to limit myself to the precise construction of the features which constitute my present improvement, as they may be varied without departing from the spirit and scope of the appended claims.

By reference to Fig. 2 it will be noted that the tube 6, which extends into the receivingchamber, delivers the mixed air and gas directly against the disk 14, which forms the closure for the upper end of the receivingchamber, and the impact of the air and gas against the disk also assists in effecting a thorough mixture in conjunction with the spreading outward of the gas and air after being delivered against the disk.

By making the shell 7 and inclosure rela tively removable access to the interior of the shell is permitted for the purpose of removing any carbon or other substance collected therein tending to obstruct the slits constituting the burner, and thus impair its eflicient operation.

While I here show and have described the slits which constitute the burner as being formed in an extension of the shell itself, I desire it to be understood that the slits may be formed in a ring or band separate from the shell and afterward united thereto, and in such instance the burner band or ring will become, in eflect, a part of the wall of the receiving-chamber, so that where I refer to forming the slits in the wall of the receivingchamber I desire it to be understood as including a separate band united to and formin a part of the receiving-chamber.

IIaving thus described my invention, what I claim, and desireto secure by Letters Patcut, is-

1. A burner of the character described, comprising a receiving-chamber, an air and gas mixer in communication with the receiving-chamber, said chamber having a closed upper utensil-supporting end, the wall of the chamber below and adjacent its closed supporting end having a plurality of short vertical narrow slots arranged around the chamber and forming a burner at the upper end only of said chamber.

2. A burner of the character described, including a receiving-chamber having a vertically-arranged burner formed around its upper portion, and an outwardly-extending flange above the burner, a closure for the receiving-chamber above the burner, the closure having a recess to receive the flange, and prongs projecting over the flange, the flange having a notch adapted to register with one of the prongs to permit the assembling and disassembling of the parts, and an air and gas mixer communicating with the receivingchamber.

3. A burner of the character described, in cluding a shell-like receiving-chamber having a vertically and circumferentially arranged burner at its upper portion, the shell having an upper open end above the burner, and a closure for the open end of the shell, the closure and the shell having detachable interlocking members, and an air and gas mixer in communication with the receivingchamber.

4. A burner of the character described, including a shell-like receiving-chamber having a circumferentially and vertically arranged burner at its upper portion, and an outwardly-extending flange above the burner, a closure for the upper end of the shell which includes a ring having a recess in its under side, a disk placed in the said recess, the recess adapted to receive the shell flange outside of the disk, the ring having members adapted to interlock with the said flange.

5. An improved burner, including a receiving-chamber the wall of which is provided with a plurality of upwardly-arranged slits circumferentially assembled in respect to the receiving-chamber, the walls between the slits being arranged to form deflectors for t the issuing mixture, and an air and gas mixer in communication with the receivingchamber.

6. An improved burner, comprising a re ceiving-chamber the wall of which is provided with a plurality of upwardly-extending slits arranged circumferentially in respect to the receiving-chamber, the walls of the slits extending at an angle to the wall of said chamber for the purpose described.

In testimony whereof I afflx my signature in presence of two witnesses.
